The first day of competition at Nike's elite football training camp The Opening was highlighted by injuries to two elite players and strong performances from two of Alabama's top targets in the 2013 recruiting class.

Day One of competition, held at Nike's corporate headquarters in Oregon, was focused around the SPARQ Rating National Championship, a series of combine-style events designed to measure speed, power, agility, reaction and quickness. Plano, Texas linebacker Mike Mitchell took home the title but Alabama committed running back Altee Tenpenny wowed scouts and fellow participants with a 4.42 forty-yard dash time and earned comparisons to Trent Richardson from ESPN analyst Tom Luginbill. Tenpenny missed all of his junior season with an ankle injury that required surgery but appeared to be operating at 100 percent on Friday.

Finishing third in the SPARQ challenge was Yulee, Florida running back Derrick Henry, a former Georgia commit who recently named Alabama the leader for his services. Henry, a 240-pound jumbo athlete, earned rave reviews for his athleticism at the event after posting a 4.45 forty time and a 42-inch vertical leap, the top mark at the event.

Also competing in the SPARQ finals was Alabama committed tight end O.J. Howard, rated one of the top tight end prospects in the country by the major recruiting services. In an interview with 247Sports, Howard reiterated his commitment to Alabama despite his plans to take official visits to other schools this fall.

"It's a done deal. Alabama is what it is," Howard said.

Not competing in the event were two of the top prospects in attendance, linebacker Reuben Foster and cornerback Vernon Hargreaves. Foster, an Alabama commit and recent enrollee at Auburn High School, injured his hamstring running a forty-yard dash early in the day and told 247Sports' Keith Niebuhr he does not expect to participate in any of the remaining events.

Competition will continue tomorrow with group play in the 7-on-7 event, which will feature Tide quarterback commit Cooper Bateman and cornerback commit Maurice Smith as well as Auburn tight end commit Arshad Jackson. Highlights from the competition will air on ESPNU beginning at 7 p.m.
